5 Unpacking and placement of the Millennium The Lyngdorf Millennium is heavy and has no built in handles. Unpacking it can be a little bit tricky. To prevent back or toe injuries, we strongly recommend you get someone to help you when it's time to lift the amplifier out of the box. Or open the box, fold out the carton flaps, without removing any packaging material, carefully turn the box upside down and simply remove the box from the amplifier. When you have carefully removed the unit and accessory kit from the carton, visually check for shipping damage. Contact both the shipper and Lyngdorf Audio immediately if the unit bears any sign of damage from mishandling. All Lyngdorf Audio equipment is carefully inspected before leaving our factory. KEEP SHIPPING CARTON AND PACKING MATERIALS for future use or in the unlikely event that the unit needs servicing. If this unit is shipped without the original packing, damage could occur and void the warranty. Place the Lyngdorf Millennium near the digital sources, thus keeping interconnects reasonably short. The Millennium may be placed on a shelf or in a cabinet where it's easy to operate. Note that adequate clearance for the AC cord, speaker cables and interconnects must be left behind the Millennium. Due to the Millennium's high efficiency, it won't get very warm even after hours of operation. This will give you great flexibility in terms of placement. Just make sure that the ventilation slots at the upper section of the back panel are not covered

6 Accessories You should find the following in the accessory kit: 1. One mains cord 2. This manual 3. Remote control 4. Programming cable (RS232 Cable for firmware upgrade from a PC) Operating voltage The Millennium is available in a version for 115V mains voltage and in a version for 230V mains voltage.

8 Quick set-up A. Connect your speaker cables to the terminals on the back panel. The speaker impedance should be 4-16 Ohms. If the speakers can be bi-wired, use both sets of terminals. Make sure that the red (+) terminal gets connected with the corresponding positive (+) terminal on your speaker. European versions of the Millennium will not accept banana plugs. Do not attempt to remove the plastic safety plugs, use spades or simply bare wires. B. Connect your CD/DVD/MD/DAT player to one of the digital inputs or an analog source to the A.l.M. Turn on the power to your source. C. Turn on the Millennium with the power button (1). D. Press the analog or digital (2/4) input selector once. The Millennium will now boot up and you must select the input where you connected the source. If the Equibit logo is flashing, press the input selectors 2 or 4 to find the right source. When the Millennium detects a signal, the logo will stop flashing. E. Adjust the volume with the wheel (3) to a moderate level. F. Activate your digital or analog source and adjust the volume. If you experience any problems during this procedure, please refer to the following pages for a more detailed explanation of the set-up

9 Front panel Fig 1: Millennium front panel. Controls The buttons/controls on the front panel of the Millennium can all be used either with direct presses on the front or by operating the similar keys on the included remote control. All keys on the front except from the Mains switch (1) can be found on the remote control as well. (1) Mains switch. Powers the Millennium on/off. Standby mode is selected with the remote control only. (2) Analog input selector. The analog input selector is only active when the optional Lyngdorf Analog lnput Module is connected to the Millennium. (3) Volume control wheel & display (4) Digital Input selector Changes to Digital input, or if already selected, cycles to the next Digital input. The wheel 5) Lyngdorf logo & Standby indicator 6) Analog input indicator 7) Digital input indicator 8) Equibit logo & input lock indicator 9) Digital input indicator - 9 -

10 Adjusting the volume The volume can be adjusted by turning the big wheel or pressing volume up/down on the remote control. The volume level is displayed in decibels and is adjusted in uniform steps of 0.1dB. A setting over 88.0dB is not recommended as this corresponds to max output with full scale digital input. However, if a CD isn t recorded in full scale, the volume can be turned up further than 88.0dB without any clipping/distortion. Pre-set Volume When the Millennium is turned on, the volume is set to a pre-programmed value. This level can easily be changed; adjust the volume to the desired level, press the A and D buttons Simultaneously for 2 seconds. The display will confirm the setting by flashing the volume and the amplifier automatically enters standby mode. Maximum output level The volume control with its low-friction, high precision ball bearings can easily spin up to full output. To prevent damage to your speakers, a maximum volume level can easily be programmed, you can find out how to do this in the section Remote Control. Power At a first glance, the operation of this very accurate db scaled volume control may come as a bit of a surprise. Normal operation will be at levels that seem to be very close to the maximum power of the amplifier. The db s scale is not linear Volume level corresponds to full scale input from e.g. a CD-player. 88dB 150 W 85dB..75 W 82dB..30 W 79dB..15 W 76dB 3 W 73dB 1.5W Keep in mind that the db scale is not linear, a 10dB increase corresponds to 10 times the power level and a 3dB increase equals 2 times the power. Set the dimmer display light control When the Millennium is in operational mode (ON), three levels of display-light settings are possible. The DIM function on the remote control (explained later) toggles between: A. Maximum light B. Dimmed C. Dimmed and volume display/input indicators off Regardless of this setting, any change in display information activates maximum light for two seconds. Polarity You can switch the polarity 180 degrees with the remote control (explained later). The display confirms the polarity with either "pos" or "neg"

11 Mute When "Mute" is activated from the remote control the display shows "---" and the amp will be muted. Press the "Mute" button again to deactivate the mute status. If the volume is changed when Millennium is muted, the display will show the volume for 3 seconds. Advanced Set-up Check the mains voltage Attempting to operate the Millennium at an incorrect voltage can damage the unit! Power is supplied via the lec-connector on the back panel. Neither the voltage nor the line frequency setting may be changed by the user. Make sure that the label on the rear panel of the Millennium indicates the correct AC operating voltage for your country. When the power switch (1) is pressed - the standby circuitry, which controls the mains relay will be activated. The amplifier will start in standby mode indicated by the red Lyngdorf logo. After a few seconds, the amplifier can be switched into operational mode by pressing any of the two input selector (2 or 4) buttons or using the power button on the remote control. In operational mode, the display located in the wheel will be visible to bring the amp back to standby mode, press the power button on the remote or press the input selector buttons simultaneously for 2 seconds. This will also default the volume setting (See section on volume control)

12 Rear panel Fig 2: Millennium rear panel. Do not cover or obstruct the ventilation slots on the rear panel. 1) Speaker terminals 2) AD Converter Input 3) D4 Input AES EBU 4) IEC Mains power connector 5) Digital Outputs D AES EBU 6) Digital Output D 7) RS 232 Input and Output 8) Speaker terminals 9) Digital Input D1 10) Digital Input D2 11) Digital Input D3A SPDIF 12) Digital Input D3B Optical 13) Analog Output R 14) Analog Output L There are 4 digital inputs on the back panel corresponding to the 4 input indicators at the right hand section of the display: DI - RCA input D2 - RCA input D3A - Digital Input D3A SPDIF D4B - Digital Input D3B Optical The D (4) button on the front panel and on the remote control is used to toggle between the inputs

13 Digital Output The selected analog or digital input source is relayed to the digital output. Use the output for recording CD s etc. Analog Inputs One of the two 5-pole XLRs is dedicated for the optional Millennium ADC, which will be clock synchronised and powered by the Millennium. When the Millennium ADC is connected, one of four analog inputs can be selected by toggling through input Al to 44. When the Millennium ADC is not present, the AI indicator will flash and the Millennium returns to the previous digital input. Address setting for network operation When used in a network in connection with either a RCS/TCS or another Millennium it is essential to set both the communication speed and address correctly. The address usage in a network is restricted by the following rules: Address Functionality Comment 0 Reserved Normally not used 1 Master Master, TCS, RCS 2-.. Slave Slave If more than one amplifier is present in the network different addresses must be appointed to each amplifier by the Millennium software. The INPUT/AUX connectors on the back panel are used for connectivity over standard RJ12 cables in a suitable length. For Slave amplifiers the input is used to pass information from the Master or a RCS/TCS to the amplifier. For Master amplifiers the broadcast information will be passed to the slave on the AUX connector which also passes any input information in a daisy chain to the next Lyngdorf product

14 Remote Control The remote control is used to access the Millennium and replicate some of the buttons directly accessible on the front panel. The four buttons used for selecting which device to control are described below. To control the Millennium the AMP key should be pressed. Amp Selects the remote for operation with Millennium or any Lyngdorf amplifier. RCS No function. CD - Selects the remote for operation with a Lyngdorf CD Player. Tuner No function. Standby The standby button toggles the Millennium between active On and standby mode. Digital Changes to Digital input, or if already selected, cycles to the next Digital input. Analog Changes to Analog input, or if already selected, cycles to the next Analog input. Button 1-8 Preset 1-7 can be selected with buttons 1-7, default presets are all linear bypass, and preset selection of the active preset will only affect the sound after changing the preset contents with the DSP software. Button 8 selects bypass. UP/DOWN and Channel +/- Cycles in either Analog or Digital input. Volume Up/down Changes volume in the chosen direction Mute Toggles Mute function on/off Some special functions can be controlled by pressing Info first followed by a numeric key: Info+1 Shows the software version in the display. Info+2 Show the device address in the display. Info+3 Increments device address by one and shows the new address. Info+4 Decrements device address by one and shows the new address. Info+5 Toggles Master/Slave. The display shows -r- for master and -c- for slave. Info+6 Change display light dimmer. Info+7 Toggles baud rate 9600/ The display shows either 960 or 576. Info+8 Changes polarity pos/neg. The display shows -P- for pos. and -n- for neg. Info+9 Stores actual volume as maximum volume level. The display shows either on or OFF The Millennium can act as Master in a set-up with more than one Millennium amplifier. In this case the remote control is active on the Master Millennium, and disabled on the Slave Millennium which is operated via the broadcast codes. All information on usage is passed on to the slave i.e. on/off, volume, mute, preset

15 Front panel operations The operations of the remote control receiver can be bypassed on the front panel for the Millennium. Bypassing the remote control is done with a long press on the Analog left selection key A. When the remote is turned off the Lyngdorf Logo blinks twice after a 2 sec. press. If the remote functionality is turned on the Lyngdorf Logo blinks once.

19 Trouble Shooting Protection Mode A sophisticated monitoring circuit controls the operation of the amplifier. When an error is detected, the amplifier shuts down into protection mode immediately and indicates the status by flashing the Lyngdorf logo. Protection mode can be triggered by: 1. Overload/short-circuit of the speaker outputs (limits current to approx. 35 Amps) 2. DC defected at the speaker outputs; this can be due to extreme program material. 3. Internal power failure burned fuses etc. 4. Mains supply voltage is too low or too high. 5. Overheating of the amplifier. Most problems are temporary Most of the above mentioned error conditions are normally temporary. When the Millennium goes into protection mode, switch off the power and inspect the amplifier. Check the speaker cables, feel if the cover is very hot. Turn on the amplifier again to see if normal operation mode may be resumed. If the error condition persists, the Millennium will return to protection mode immediately. If this is the case, the Millennium needs authorised service. NOTE: No bridge coupling is possible. The frequency response of the Millennium extends down to DC. Playback of material with extreme infrasonic program material may cause the amp to go into protection mode in order to protect the speakers
